Chemistry Reference Sheet: Formulas, Elements, and Prefixes

Vocabulary flashcards covering chemical element symbols, density and atomic mass formulas, constants, and covalent prefixes from the lecture handout.

Density

$$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$$

Percent Abundance

$$\text{Percent Abundance} = \left(\frac{\text{Number of Atoms of Isotope}}{\text{Total \# of Atoms}}\right) \times 100$$

Relative Mass (RM)

$$\text{Relative Mass (RM)} = \text{RA} \times \text{Mass}$$

Weighted Average Mass

$$\text{Weighted Average Mass} = \text{RM}_1 + \text{RM}_2 + \dots$$

Density Units

$\text{g/mL}$ or $\text{g/cm}^3$

Density of Water

$$1.0\,\text{g/mL}$$
